Question 1 :
A body of mass 40 gram is moving with a constant velocity of 20 $ms^{-}$ $^{1}$ on a horizontal frictionless table. The force acting on the body in horizontal direction is:

Question 2 :
A weight {tex} W {/tex} is supported by two cables as shown. The tension in the cable making angle {tex} \theta {/tex} with horizontal will be the minimum when the value of {tex} \theta {/tex} is<br><img style='object-fit:contain' src="https://storage.googleapis.com/teachmint/question_assets/NEET/5e101dcf4faa335027dc7aed"><br>

Question 3 :
A body is rolling on the ground with a velocity of $1\ m/s$. After travelling a distance of $5\ m$, the body stops. The coefficient of friction is:

Question 4 :
A block {tex} \mathrm { B } {/tex} is pushed momentarily along a horizontal surface with an initial velocity V. If {tex} \mu {/tex} is the coefficient of sliding friction between B and the surface, block B will come to rest after a time<br><img style='object-fit:contain' src="https://storage.googleapis.com/teachmint/question_assets/NEET/5e101e694faa335027dc7b6b"><br>

Question 5 :
A particle of mass {tex} m {/tex} rotates with a uniform angular speed {tex} \omega . {/tex} It is viewed from a frame rotating about the Z-axis with a uniform angular velocity {tex} \omega _ { 0 } . {/tex} The centrifugal force on the particle is:

Question 6 :
A horizontal force of {tex} 10 \mathrm { N } {/tex} is necessary to just hold a block stationary against a wall. The coefficient of friction between the block and the wall is {tex} 0.2 . {/tex} The weight of the block is<br><img style='object-fit:contain' src="https://storage.googleapis.com/teachmint/question_assets/NEET/5e101e644faa335027dc7b66"><br>

Question 7 :
In the figure shown, the pulleys and strings are massless. The acceleration of the block of mass {tex} 4 m {/tex} just after the system is released from rest is {tex} ( \theta ) {/tex} {tex} \left. = \sin ^ { - 1 } 3 / 5 \right) {/tex}<br><img style='object-fit:contain' src="https://storage.googleapis.com/teachmint/question_assets/NEET/5e101c92de596850506e367d"><br>
